Optix was developed a decade ago and doesn’t require RTX cards. It run on any Maxwell or newer card. It’s NVIDIA’s version of RadeonRays.
What NVIDIA is trying to sell people is a denoiser.
And are you sure RT Cores even exist or are they just tensorcores by a different name?
Battlefield V Ultra 1080p RTX on is ~63 FPS average (not minimum FPS, but average), which means it will regularly dip below 60 in practice.
> Also last I read, RTX really isn't designed for offline raytracing and doesn't really bring much to the table. Its use is in realtime.
On the contrary! RTX Cores are a hardware-accelerated BVH-traversal. That has HUGE implications for the offline rendering scene.
See NVidia Optix for details: https://devblogs.nvidia.com/nvidia-optix-ray-tracing-powered...
IMO, this is the killer-feature of RTX. Accelerating those Hollywood Renders from hours-per-frame to minutes-per-frame. NVidia Optix takes industry-standard scene trees and can use the RTX Cores to traverse them for hardware-accelerated raytracing.
Or more specifically: coarse AABB Bounds checking, which is a very compute & memory heavy portion of the Raytracing algorithm.
Even if RTX is too slow for video games, any improvement to offline rendering is a huge advantage.
